Now assume Host A IP address is 20.5.5.50, Host B IP address is 20.5.105.150, and subnet mask is 255.255.255.0. Again this may not be a standard Network class (class A, B or C), but you draw your conclusion based on subnet mask definition. What are the Network IDs for Host A and B ? Are they in the same LAN? What is the valid IP range for Host A's network? What is the valid IP range for Host B's network
